How much does a message cost?

0 credits
Plan mode

Discussion only, no changes applied: you're never charged.

Usage-based
Build mode

Every message — questions included — is billed for the actual AI work, in fractions of a credit: minimum 0.1, never more than 5 credits.

0 credits
Try to fix

Automatic attempts to fix errors are always free.

Note: the cost of a build message is proportional to the AI work actually measured (the tokens the model consumes), rounded to a tenth of a credit. A turn that gets interrupted or fails without delivering anything costs nothing. AI-generated images are included.

Everything you need to publish.

Every plan includes the same engine. What changes is the scale.

The HEKU engine

Describe the site you want: the engine builds it in a live preview, section by section, and fixes errors on its own.

AI-generated images

The engine creates the photos for your site, tailored to your brand. No stock images that look like everyone else's.

Forms and inquiries

The forms on your published site are real: they collect your customers' name, email, and message.

Live in one click

Publish to your heku.dev address with HTTPS: your site is live right away, with nothing to configure.

Code export

Starting with the Pro plan, you can download your project as a .zip anytime. No lock-in: the code is yours.

Solid infrastructure

HEKU runs on enterprise-grade cloud (Vercel and Supabase): encrypted connections and isolated environments for each project.
